I have long running problem with battery drain on 2007 1.2 polo. Drain is 0.3 amp (battery goes flat over a couple of days) - when draining the throttle body is running intermittently and relay 429 is warm - when fuse 40 (ECU) is pulled the drain stops and even when fuse 40 is put back in the drain doesnt start again until the car is started. I tried changing relay 429 but then the power steering pump packed in - coincidence?? - any ideas
